Correct Answer: Option C
Explanation
Aginomoto (MSG) is NOT extracted from seaweeds:• Aginomoto is the brand name for Monosodium Glutamate (MSG) — a flavour enhancer known as the 'umami' taste.• Production: Industrial fermentation of molasses (sugarcane) or glucose using Corynebacterium glutamicum (overproduces L-glutamate) → neutralised with NaOH to form MSG.• MSG was originally isolated from kombu (a seaweed) in 1908 by Kikunae Ikeda, but modern production is exclusively by bacterial fermentation.Seaweed-derived products:• Agar: extracted from red algae (Gelidium, Gracilaria); used as solidifying agent.• Alginate: extracted from brown algae (Ascophyllum, Laminaria); used as thickener, encapsulation agent.• Carrageenan: extracted from red algae (Chondrus, Kappaphycus); food gelling agent.• Fucoidan: sulfated polysaccharide from brown algae.Conclusion: Aginomoto (MSG) is NOT commercially extracted from seaweeds — it is produced by bacterial fermentation.Answer: Aginomoto (MSG) is NOT extracted from seaweeds; it is produced by microbial fermentation of sugars.
